Senior Full Stack Java Developer Jobs in Kansas (NOW HIRING)

About AGENCYOF

AGENCYOF is a strategy-led, performance-driven agency working across hospitality, animal health, outdoor equipment, construction, technology, and mission-driven brands. We are 11 people. We move fast. We operate lean. And we care deeply about the quality of the work and the strength of our client relationships.

We are not a layered organization. You will work directly alongside our CTO. You will contribute to real client work from day one. If you want mentorship with actual stakes attached to it, you'll find it here.

The Role

This is an early-to-mid career opportunity for a developer who is ready to grow fast in a hands-on, high-ownership environment. You will work directly with our CTO across the full development lifecycle building client-facing websites and web applications, contributing to technical decisions, and developing the skills and instincts to take on increasing responsibility over time.

You are not here to maintain. You are here to build.

What You'll Do

Build for Clients

• Develop client-facing websites and web applications across a variety of industries and project types
• Take a functional specification and independently produce a deployable, production-ready application
• Deploy and maintain applications across platforms like Vercel, DigitalOcean, and AWS
  

Collaborate and Contribute

• Work closely with the CTO on technical decisions and feature delivery
• Participate in code review and adhere to version control standards
• Research and present emerging tools, technologies, and development practices
  

Use AI With Judgment

• Leverage AI-assisted development tools like Cursor and Claude Code as productivity multipliers
• Be transparent about how and where AI tools are used
• Know the difference between AI as a crutch and AI as an accelerant
  

What Success Looks Like

By 6 Months:

• You've shipped real work for real clients with minimal oversight
• You're contributing meaningfully to technical conversations with the CTO
• You understand how AGENCYOF's development practice connects to the broader agency

By 12 Months:

• You've expanded your technical range beyond your starting point
• You're trusted to own a project end-to-end
• You've identified at least one process, tool, or workflow that made the team better
  

Who Thrives Here

• Someone who takes initiative before being asked
• Someone genuinely curious about emerging tools and how to apply them
• Someone who sees client work as a feature, not a distraction from "real" development
• Someone who can receive feedback, adapt, and come back sharper
  

Who This Is Not For

• Someone who needs every task defined before they can move
• Someone uncomfortable working in ambiguity or across multiple project types simultaneously
• Someone who treats AI tools as a shortcut around understanding
• Someone who wants to specialize early and stay narrow
  

What You Bring

Required:

• Foundational knowledge in software engineering through a bootcamp, associate's, or bachelor's degree in a related field
• Working knowledge of React, JavaScript, Next.js, and Tailwind CSS
• Proficiency with Git-based version control including branching and pull request workflows
• Demonstrated experience with AI coding tools
• Genuine interest in UI/UX design principles
• Ability to independently deploy to Vercel or equivalent
  

Preferred:

• Experience with Laravel and PHP
• Proficiency in Linux terminal environments and hosted server infrastructure
• Familiarity with AWS or DigitalOcean
• Experience with native mobile apps or PWAs
• Relevant security compliance certifications
  

Benefits

• 100% employer-paid health, dental, vision, and short-term disability
• 3% Simple IRA match day one
• Flexible PTO we trust you to manage your time

How to Apply

Submit a current resume, a link to your GitHub profile, and a brief paragraph describing a project you've built what problem it solved and what you learned from it. Links to live projects or repositories are strongly encouraged.
